IS200TRPLH1A

The GE Mark VI IS200TRPLH1A serves as a primary trip terminal board. General Electric's IS200TRPLH1A board component is used in the company's Mark VI system for regulating industrial gas and steam turbine systems.

• The Mark VI was one of General Electric's last Speedtronic systems to be developed and released. This board is often only found on steam turbines. It is compatible with Mark VI and Mark VIe systems.
• It is a terminal card for a large steam turbine primary trip. It is the primary Overspeed protection on larger steam turbine systems.
• The board is controlled by the turbine protection controller card, which is usually a VTUR or PTUR board. It also works in tandem with a TREL board to provide ETDs with emergency/primary interfaces. The TRPL board delivers the negative side of the 125 VDC to the trip solenoids, while the TREL board gives the positive side. Up to three trip solenoids can be connected to these boards.
• Two big terminal strips with a total of 48 connector points populate the board. MOV diodes, resistors, transistors, integrated circuits, wire jumpers, and nine magnetic relays are also included, as well as three-d-shell connectors and other plug connectors.
• Three voting circuits interface with three trip solenoids via relays. Solenoid suppression and voltage monitoring are included in trip circuits, and solenoids use two out of three contact voting.
